Issues in adding custom widget in experience builder

[NehaKshirsagar1]

Hi, I am getting issues in adding custom widget in experience builder 11.1 version.

Custom widget is working fine in developer version of Experience builder. However , it gives me errors whenever I deployed same widget & using in Experience Builder Application. 

I have used exactly same process as given in documentation.

Process : 1. https://www.esri.com/arcgis-blog/products/arcgis-enterprise/developers/add-experience-builder-custom...

2. https://doc.arcgis.com/en/experience-builder/11.0/configure-widgets/add-custom-widgets.htm

Looking forward to your positive response.

Hi @NehaKshirsagar1 - can you please give further context and information to the issues/errors you are receiving?

[NehaKshirsagar1]

Hi @CamMuller, Please check this screenshot for the error I am getting for deployed custom application .. It throws an Error: Cannot read properties of undefined {reading featureLayer}

 

Same code is running as expected in Experience Builder developer version

Some things to check:

1. Your manifest.json indicates Experience Builder 1.12, but Enterprise 11.0 is on Experience Builder 1.8. If you are not using features from the latest versions of the Javascript API, consider downgrading your required version in the manifest.
2. The error indicates that your widget is expecting a featureLayer and can't find it. Maybe you need to add the map to the experience before you add your table widget.
3. Make sure you do not have any naming conflicts with between your widgets or with any ESRI widget. I created a custom BasemapGallery that broke when ESRI released their version. To clear the error, I had to remove my widget from the Experience Builder folder structure, rename it, stop the server, re-add it to the Experience Builder directory, and restart the server.

Hi @JeffreyThompson2 ,

I have tried with changing version in manifest , added Map/featureLayer in map and then tried with widget; However, I am still facing this error. Error: Cannot read properties of undefined {reading featureLayer}

It would be great if you please help me in this issue..

I don't know if I can get to the bottom of this, but here are some more things to look into.

1. You said that this code is working in your local developer environment, but not on Enterprise. Are you sure that the code in both places is exactly the same? If so, think about what may be different about these environments.
2.  Open up your developer tools and find what line of code is throwing the error. Start your investigation there.
3. Does the error occur immediately after adding the widget to the Experience or does it happen after some sort of interaction? Does it run in Preview mode?
4. Looking at some of your code I assume you copied the ESRI table widget as the base for your widget. Are you sure if it is backwards compatible with the earlier API version? There have been some pretty big changes to the API lately.
5. My linter is detecting many potential errors in your setting.tsx file. Sometimes the linter is wrong, but not often. Some lines I am especially suspicious of causing problems: 

   Seeing the linter flag brackets and javascript reserved words is a big red flag of some sort of syntax error.

Hi  JeffreyThompson2,

I am trying to install developer version of experience builder 1.8 to check the widget code ; However, it's not letting me use it with cross-env issue.

Tried with fresh installing of 1.8 version is having error in client server illustrated below :

Please help me in resolving this problem.

[JeffreyThompson2]

Did you download the 1.8 software package and run npm ci? Are you trying to load other custom widgets from higher versions?

More fundamentally, what is your goal with this widget? What can your widget do that the default table widget can't? Could you build your widget from scratch or the javascript API? I often find starting fresh to be easier than trying to modify ESRI's code.

Hi Jeffrey,

I will be trying to rebuild the widget again in Experience Builder 1.8 version..
